Tell us what you are trying to do?I am deleting one of the posts in a many to many relationship and want to know if Toolset will automatically delete the relationship or must I do it before I delete the post?
Yes, the records of the associations are deleted when any one of the connected posts are deleted (but not if they are only trashed).
The associations are recorded in a combination of the wp_toolset_connected_elements and wp_toolset_associations tables, and the entries are deleted from both.
